Study the following reaction carefully. what classification should this reaction have?
4al + 3o2 = synthesis, decomposition, single replacement, double displacement

synthesis

Explanation:

  The reaction equation properly written is shown below:

               4Al + 3O₂ → 2Al₂O₃

  A synthesis reaction is a form of combination of atoms. It involves the formation of a single product from two or more reactants.

Decomposition is the formation of two or more products from a single reactant.

Single replacement is a reaction in which one substance is replacing another.

In double displacement, there is an actual exchange of partners to form new compounds.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
